Bioinspired Synthesis of High-Strength Bulk CO Mineralized Ceramics at Room Temperature.

Traditional high-temperature fabrication methods for ceramics suffer from significant energy consumption and limit the development of advanced ceramics incorporating temperature-sensitive materials. While bioinspired mineralization provides an effective strategy to realize the room-temperature preparation of ceramics, scaling up production remains a challenge. Herein, we demonstrate a room-temperature procedure for the fabrication of large-scale ceramics by using the carbonation reaction of sodium alginate (SA)-doped γ-dicalcium silicate (γ-CS) compacts.

C4 cereal and biofuel crop microbiomes.

Microbiomes provide multiple life-support functions for plants, including nutrient acquisition and tolerance to abiotic and biotic stresses. Considering the importance of C4 cereal and biofuel crops for food security under climate change conditions, more attention has been given recently to C4 plant microbiome assembly and functions. Here, we review the current status of C4 cereal and biofuel crop microbiome research with a focus on beneficial microbial traits for crop growth and health.

The osmotic stress-activated receptor-like kinase DPY1 mediates SnRK2 kinase activation and drought tolerance in Setaria.

Plant genomes encode many receptor-like kinases (RLKs) that localize to the cell surface and perceive a wide variety of environmental cues to initiate downstream signaling cascades. Whether these RLKs participate in dehydration stress signaling in plants is largely unknown. DROOPY LEAF1 (DPY1), a leucine-rich repeat (LRR)-RLK, was recently shown to regulate plant architecture by orchestrating early brassinosteroid signaling in foxtail millet (Setaria italica).

Identification of the major QTL for adult plant resistance to wheat powdery mildew.

Developing effective and durable host plant resistance is crucial for controlling powdery mildew, a devastating disease caused by f. sp. ().

Kinase activity is required for the receptor kinase DROOPY LEAF1 to control leaf droopiness.

Plants have evolved many leucine-rich repeat receptor-like kinases (LRR-RLKs) that control all aspects of plant life in a kinase-dependent or -independent manner. DROOPY LEAF1 (DPY1), which is a subfamily II LRR-RLK authentic kinase, controls leaf droopiness by negatively regulating early brassinosteroid (BR) signaling in foxtail millet. In this study, we proved that overexpressing kinase-inactive DPY1 does not rescue the droopy leaf phenotype of plants because the mutated DPY1 cannot repress BR signaling, suggesting that kinase activity is required for DPY1 to control BR signaling.

Wheat FRIZZY PANICLE activates VERNALIZATION1-A and HOMEOBOX4-A to regulate spike development in wheat.

Kernel number per spike determined by the spike or inflorescence development is one important agricultural trait for wheat yield that is critical for global food security. While a few important genes for wheat spike development were identified, the genetic regulatory mechanism underlying supernumerary spikelets (SSs) is still unclear. Here, we cloned the wheat FRIZZY PANICLE (WFZP) gene from one local wheat cultivar.

DROOPY LEAF1 controls leaf architecture by orchestrating early brassinosteroid signaling.

Leaf architecture directly determines canopy structure, and thus, grain yield in crops. Leaf droopiness is an agronomic trait primarily affecting the cereal leaf architecture but the genetic basis and underlying molecular mechanism of this trait remain unclear. Here, we report that DROOPY LEAF1 (DPY1), an LRR receptor-like kinase, plays a crucial role in determining leaf droopiness by controlling the brassinosteroid (BR) signaling output in , an emerging model for Panicoideae grasses.

A Genome-wide View of Transcriptome Dynamics During Early Spike Development in Bread Wheat.

Wheat spike development is a coordinated process of cell proliferation and differentiation with distinctive phases and architecture changes. However, the dynamic alteration of gene expression in this process remains enigmatic. Here, we characterized and dissected bread wheat spike into six developmental stages, and used genome-wide gene expression profiling, to investigate the underlying regulatory mechanisms.

FAR-RED ELONGATED HYPOCOTYL3 activates SEPALLATA2 but inhibits CLAVATA3 to regulate meristem determinacy and maintenance in Arabidopsis.

Plant meristems are responsible for the generation of all plant tissues and organs. Here we show that the transcription factor (TF) FAR-RED ELONGATED HYPOCOTYL3 (FHY3) plays an important role in both floral meristem (FM) determinacy and shoot apical meristem maintenance in Arabidopsis, in addition to its well-known multifaceted roles in plant growth and development during the vegetative stage. Through genetic analyses, we show that WUSCHEL (WUS) and CLAVATA3 (CLV3), two central players in the establishment and maintenance of meristems, are epistatic to FHY3 Using genome-wide ChIP-seq and RNA-seq data, we identify hundreds of FHY3 target genes in flowers and find that FHY3 mainly acts as a transcriptional repressor in flower development, in contrast to its transcriptional activator role in seedlings.

Novel genomes and genome constitutions identified by GISH and 5S rDNA and knotted1 genomic sequences in the genus Setaria.

Background: The Setaria genus is increasingly of interest to researchers, as its two species, S. viridis and S. italica, are being developed as models for understanding C4 photosynthesis and plant functional genomics.
